Eaton TWBS2062 Thru-Wall Barrier Sealing Block - UL Listed
Part Number: TWBS2062
Quick Summary
The Eaton TWBS2062 Thru-Wall Barrier sealing block assembly provides reliable thru-wall sealing for marine electrical installations. In harsh environments, inadequate sealing leads to water ingress, corrosion, and costly downtime. UL certification for Firestop Devices (US and Canada) and related listings underpin regulatory compliance, while the product’s ordinary/non-hazardous location suitability broadens installation scope. Designed with elastomeric material and a 2-frame-space footprint, it delivers robust, adaptable protection for multiple openings. This solution supports efficient, durable shared-wall installations and aligns with typical Crouse-Hinds TW series assemblies, offering tangible business value through reduced maintenance and improved reliability in marine contexts.
